Tina Fey working on Mean Girls musical this summer

Tina Fey is planning to spend the "whole summer" working on the Mean Girls musical.

The 45-year-old star has been busy in recent months with hit Netflix series Unbreakable Kimmy Schmidt, which she created and appears in. But since the show's star Ellie Kemper recently revealed she is pregnant with her first child, a break from the show will give Tina the time she needs to write the much talked about musical adaptation of 2004 hit movie Mean Girls.

"We’re working on the musical adaptation, and thanks to Ellie Kemper’s pregnancy, we have this whole summer to work on it,” Tina told a delighted audience during a Tribeca Film Festival panel event on Tuesday night (19Apr16).

Tina, who wrote the screenplay for the film, will be penning the stage show with husband Jeff Richmond. However, she isn't sure whether to keep the plot as it is, or to bring it up to date by including technological developments like social media.

"The thing about social media is that it doesn't dramatise well," she admitted. "It's been a question of like, 'Yeah, do you take out things that are now outdated like three way calling and stuff?'"

Tina and Jeff are parents to 10-year-old Alice and four-year-old Penelope. But while it's all about laughs when they're at work, it's a different story at home, the comedian laughed.

"I have a poodle that I never trained right. So, at least once a night, I'm doing a Clorox wipe on the kitchen floor," Tina admitted. "That's mostly what our life is, cleaning up urine."

Another person Tina has frequently worked with is Amy Poehler, her co-star on Saturday Night Live and comedy films such as Baby Mama.

But while there has been a lot of calls for the pair to work together on a series, Tina isn't confident they would work well over a longer committment.

"We're regarded as a comedy team, which is totally fine by me," Tina said. "People sometimes used to say, 'Why don't you guys do a series together?' or whatever. And the funny thing is that I think we both know this to be true, it's because we're actually both alphas. So, it works in shorts spurts, but I don't know if it would make a real dynasty."
